I'm having trouble wrapping a subset of d3-force using jooc. The library does not use object properties and instead implements fused getter-setter functions, e.g.
simulation.force("x", d3.forceX()) // setter
simulation.force("x") // getter
I'd like to find a way to emulate the same kind of polymorphism in OCaml. Here's what I currently have
module Force = struct
class type force = object
(* not important *)
end
let x (): force Js.t = Js.Unsafe.meth_call __d3 "forceX" [||]
class type simulation = object
method force : string -> #force Js.t -> unit Js.meth
end
let simulation nodes: simulation Js.t =
Js.Unsafe.(meth_call __d3 "forceSimulation" [|inject nodes|])
end
And here's what I'm after
let s = Force.simulation nodes in begin
s##force "x" (Force.x ())
s##force "x" (* wishful thinking *)
end
class type simulation = object
method force_set : Js.js_string Js.t -> #force Js.t -> unit Js.meth
method force : Js.js_string Js.t -> #force Js.t Js.meth
end
Js.js_string Js.t
. force
and force_set
will both bind to force
. Have a look at http://ocsigen.org/js_of_ocaml/2.8.1/manual/library "Method name and underscore"
